I am doing the first scenario. I thought the problem might have had to do with not closing datasets I opened with Proc IML. However, I added Close statements following my Read statement. It did not fix the problem.

You don't supply enough information, need to see some code.  What is
your basic simulation "method"? Do you?

1) set rep=1
2) create some data.
3) calculate value(s) of interest
4) append result to data set of "results"
5) do it all over and over until reps=2000
6) summarize the results of 2000 simulations.

or do you?

1) create 2000 samples of data as a somewhat large data set
2) calculate value(s) of interest (BY REP)
3) summarize

So which is it?
